.AKTIENGESELLSCHAFT, OF

GUN WITH INDEPENDENT SIGHTINGQLINIEQ To all whom it mag concern;

Be it known that we, OTTO LAUBER and FRIEDRICH STOCK, residing atEssen-ou-the- Ruhr, Germany, subjects of the German Emperor, haveinvented a certain new and useful Gun with Independent Sighting-Line,ofwhich the following is a specification.

The present invention relates to guns with independent sighting-lines;and the object of the invention is to provide, in connection with thesight-post, a device which isas compact as possible, easily accessible,and constructed to permit adjustment of the elevation of the gun-barreleither-with the sight-post or relatively thereto. This object accordingto the present invention is obtained by arranging coaxial-1y the screwmembers of two mechanisms employed for fixing the elevation and bycausing one of the said mechanisms to connect with the sight-post andthe other mechanism to connect with the gun-barrel.

In the accompanying drawings the invention is shown, by way ofillustration, as applied to a recoil-gun having a cradle capable ofhorizontal training.

In said drawings, Figure 1 is a side elevation of one embodiment of theinvention, only the parts having relation to the invention beingillustrated. Fig. 1 is a side elevation corresponding to Fig. 1 withsome parts omitted or broken away. Fig. 2 is a rear elevation of Fig. 1.Fig. 3 is a sectional view, on an enlarged scale, taken on line 3 3.Fig.1, and looking from the right. Fig. 4 is a section on line 4 4:,Fig. 3, looking from above. Fig. 5 is a section on line 5 5, Fig. 3,looking from above. Fig. 6 is a section on line 6 6, Fig. 3, lookingfrom above. Fig. 7 is a side elevation corresponding to Fig. 1 of a.second embodimentof the invention. Fig. 8 is a rear elevation of theembodiment shown in Fig. 7. Fig. 9 is a sectional View, on an enlargedscale, taken on line 9 9, Fig. 7, and looking from the right. Fig. 10 isa sectional View similar to Figs. 3 and 9, but of a third embodiment ofthe invention.

Referring to the embodiment shown in Figs. 1 to 6, inclusive, A is thepart to be elevated or the cradle of the gun, on which the gunbarrel B,also to be elevated, is slidably mounted. The cradle A is in thecustomary manner connected with the saddle C by means-of a verticaltrunnion a. The cradle is further coni Specification of Letters Patent.

nected with a training mechanism D for the horizontal movement. Throughthe medium of the hand-wheeld of the training mechanism the cradle andthe gun-barrel mounted thereon can be swung horizontally around the axisof the Vertical trunnion a. ThesaddleC is in the customary mannerjournaled in the mount J by means of the horizontal trunnions 0 and can,with the cradle A and the-gun-barrel B, be swung about the axis of thehorizontal trunnions c. The sight-post E, carrying the sight 6', iscurved in an arcthat is,-con centric with the horizontal trunnions 0whenthe training mechanism D is in its zero posi tion. The sight-post isadapted to slide in a guide-piece (0 secured to the cradle A and of acurvature corresponding to that of the sight-post. The rear face of thesight post E is provided with a. distance-scale a The gun is providedwith two screw mechanisms for fixing the elevation, one of'whichconsists of the two telescoping screws H and second pair of bevel-gearsp (f, a shaft Q,

'L, a sleeve N, bevel-gears'n p a shaft P, a

and a hand-Wheel q, and. the purpose of this mechanism is to adjust theelevation of the gun-barrel with relation to the sight-post. The secondscrew mechanism consists of a screw M, a nut S, shaped exteriorly as abevelgear, a bevel-gear W, a shaft It, asecond pair of bevel-gears 1"251a shaft'T, and a handwheel 25, and the purpose of this mechanism isto adjust the elevation of the gun-barrel with the sight-post. Thescrews of the two mechanisms are arranged coaxially to each other, thescrew L of one mechanism engaging the threads of the. screw M of theother mechanism. The elevating-mechanism: carrier K provides for theconnection of the elevating mechanism to the mount J. The shape of thecarrier K is clearly shown in Figs. 3 and 5. By means of-a pair ofhollow trun nions l: the carrier K is rotatably supported in the mount Jin such a manner that the carrier can partake in the swinging movementsof the elevating mechanisms when the elevation is adjusted. The firstmentioned of the two elevating mechanisms engages the gunbarrel by meansof a head [L of the screw H, which by means of a joint bolt 0, Fig. l,is linked to the saddle C. The position of the bolt 0 coincides with thecurvature of the sight-post, Fig. 1. The screw H is left-handaxis by thebolt ed and is prevented from rotation around its The screw L is ahollow screw. and its interior is provided with threads for the screw H.L is provided with right-handed threads and is of such a length thatthelower end of the sore-iv extends beyond the screw M. In the lower partof the outer wal of the screw' L areucut longitudinal grooves Z, intowhich feathers n of the sleeve N project. The sleeve N is arrangedrotatably but non-slida ly in a bore of the elevating-mechanism carrierK, said bore being coaxial to the screw. The feathers n, which projectinto the groove Z, force. the screw L to partake of the rotation of thesleeve N, while they permit a longitudinal movement of the screw Lrelative to the sleeve N. On the sleeve N a bevel-gear n is rigidlysecured, which meshes with the bevel-gear on the shaft P. The shaft P isjournaled in the right-hand hollow trunnion is, Fig. 3, of the carrier Kand is capable of being rotated by means of the handwheel q and theabove-mentioned gear Q q p. The second of the two elevating mechanismsis by means of the screws H and L indirectly connected with thegun-barrel, and by means of an arm F and a slide Git is directlyconnected with the sightpost E.

on its exterior with right-handed screwthreads. In the outer wall of thescrew are longitudinal grooves m, into which project feathers k, thatare secured in the bore of the carrier K coaxial to the screw M. Thefeathers k prevent the rotation of the screw M around its axis, whilethey permit a longitudinal movement of the screw relative to the carrierK. The screw M is surrounded by the bevel-gear nut S, that is arrangedin the bore of the carrier K in such a manner that it can rotate, butnot move-longitudinally. The bevel-gear r which is secured to the shaftIt, meshes with the toothed crown of the nut S. The shaft Ris journaledin the left-hand hollow trunnion is, Fig. 3, of the carrier K and isrotated by means of the hand-wheel t and the gear T t 1 To thedisk-shaped head m of the screw M an 'L-shaped arm F is secured. Theplate f of the said arm is provided with an undercut groove, Figs. 1 and4, so as to form a race that is curved in an arc whlch 1n the zeroposition of the gun is concentric with the vertical trunnion a. A slideGr is mounted to slide on said race, and the base 9 of the slide isinserted into the groove of the race.

' The slide G is provided with twoprojections forming a fork thatembraces the lower end of the sight-post. The projections are providedwith slots, Fig.- 1,,so as to form a sec 0nd race g, in which a bolt einserted through the lower end of the sight-post, can slide. The race gis curved in an arc that is concentric with the trunnio'ns k of thecarrier The exterior of the screw- The screw M of this second elevatingmechanism is provided K when the horizontal training mechanism is in itszero position. I

In Figs. 1 to 6 the relative positions of the different parts correspondto an angle of elevation of 0 and to an angle of site of 0 When i the.handwheel (1 is turned clockwise, the sleeve N is rotated through themedium of the shafts Q and P and the several bevelgears. By means of thefeathers n the sleeve N carries along with it the screwLand screws itdownwardly into the screw M, the latter being prevented from rotation bythe feathers k', and the screw Lslides with the walls of its groovesZalong the feathers n. At the same time the screw H is in the customarymanner screwed into the screw L. As a result of the said operations thegun-barrel B.

and cradle A are swung around the horizontal trunnions '0 in thedirection of elevation of the gun. At the same time theelevatingmechanism carrier K makes a slight swinging movement arounditstrunnions It 70. lhe movements above described have, no effect on therelative position of the screw M and the carrier K. The screw M, withthe arm F, has partaken of the swinging movement of the carrier K; butthe said movement has no effect on the relative position of. thesightpost and the fixed parts of the gun, as the bolt 0 of thesight-post can slide in the race g. While the sight-post E has beenstationary, the guide piece a7, that is rigidly connected to the cradleA, has, however. moved along the sight-post,.and thus the upper edge ofthe guide piece a will indicate on the scale 0 the amount of elevationor the range corresponding thereto, Fig. 2 When the horizontaltraining-mechanism D is usedthat is to say, when thh'adle with thegunbarrel is swung on the vertical trunnion a, Fig. 1-the slide (jr,carrying the sight-post, slides on the race f. The connection betweenthe sight-post and the second elevating mechanism is therefore notinfluenced by the horizontal training of the gun-barrel. If thehand-wheel q is turned counterclockwise, the direction of movement ofthe diflerent parts is reversed. The sight post retains its positionwhile the gun-barrel is lowered. When the hand-wheel t is turnedclockwise. the nut and the several bevel-gears, and the screw M,

which is prevented from rotation around its axis by the feathers k, isscrewed downwardly into the nut S. The said movement of the screw Missirnultaneously transmitted to the cradle or the gun-barrel and thesight-post, and the gun-barrel is elevated. The downward movement of thescrew M is transmitted to the. gun-barrel through the medium of thescrew L, prevented from rotating by autoblockage, andthe screw H. Thedownward movement of the screw M is transmitted to the sight-post'Ethrough the medium of the arm F'and the slide G. The movement of thesight-post with relation to the fixed parts of the gun takes place inan'arc that is coincident with the arc of movement of the bolt 0 thatconnects the screw H with the saddle C or the cradle and the gun-barrelThe movement of the screw M, that is transmitted unifbrmly to thesight-post and the' gun-barrel, therefore causes the same angularmovement of the two parts, or, in other words, the relative position ofelevation of the gun-barrel and the sightpost remains unaltered duringthe vertical adjustment of the two parts effected by operating the handwheel 6. As, however, thebolt 6 of the sight-post partakes in themovement of the post, while the arm F and the slide G are obliged tofollow the swinging movement of the elevating mechanism around thetrunnions If the bolt 0 moves in the race If the hand-wheel t is turnedcounterclockwise, the direction of movement of the different parts willbe inverted.

The embodiment shown in Figs. 7 to 9 is in all essential featuressimilar to that above described. Only the mounting of some of the partsrelatively to the carrier K is somewhat different. The positions of thesleeve N and the nut S have been transposed, the sleeve N being arrangedat the upper partof the carrier, while the nut S is arranged at thelower part ofthe carrierK. The result of this transposition is that thedirection of the inclinationof the threads of all three screws has beenchanged and that the arm is secured to the lower end of the screw M.Furthermore, the arm F projects upwardly at the outside of the mount Jand is provided with a slot f through which passes the arm 2'.

The mode of operation of the embodiment shown in Figs. 7 to 9 is exactlythe same as that of the embodiment first described.

The embodiment shown in Fig. 10 differs from that shown in Figs. 1 to 6,essentially, only in that the gear N a 12 2 P of the elevating-screws Hand L is journaled in the disk-shaped head m of the screw M.Furthermore, the feathers It" are replaced by .a projecting rod m,securedto the head m and entering a bore in the elevating-mechanismcarrier K.
